C Specification

The VkMicromapUsageEXT structure is defined as:

// Provided by VK_EXT_opacity_micromap
typedef struct VkMicromapUsageEXT {
    uint32_t    count;
    uint32_t    subdivisionLevel;
    uint32_t    format;
} VkMicromapUsageEXT;

Members

  • count is the number of triangles in the usage format defined by the subdivisionLevel and format below in the micromap

  • subdivisionLevel is the subdivision level of this usage format

  • format is the format of this usage format

Description

Valid Usage

The format is interpreted based on the type of the micromap using it.
